    that all depends on the cams. not for nothing, but stock b16 cams make power up to 8k on stock ls/vtec engines. not much power though. if you plan on going with those pistons, use itr cams. they will make power all the way up to 9k no problems. my old old setup was similiar but with 12.5:1 compression and itr cams and it made power up to 8900 slightly falling off at 9000 rpm. most people wont spin ls/vtec's over 8k due to the long rod stroke. produces more torque but loses the reliability to spin high. I spun a bearing twice at 9k after 4 months of hardcore abuse on my old old setup, two different blocks. broken in properly on a dyno and all. now im experimenting with different cranks.

    don't plan on spinning to 9,000rpm
    8,000 should be fine when dynoed and camed
    going to be my daily driver
